Under the operation of the eight groups of turning rods 41 at the bottom of the first mud turning component 4, trenches can be dug for the sludge on the surface of the conveyor belt 2. At this time, high-temperature gas is ejected from the multiple groups of nozzles 62 at the bottom of the gas collecting plate 61, and the hot gas enters the eight groups of grooves on the surface of the sludge, increasing the contact area between the hot gas and the sludge, thereby improving the drying effect of the sludge. At the same time, the sludge dried by the first drying component 6 continues to move to the right, and the nine groups of turning rods 41 at the bottom of the second mud turning component 5 are used to dig trenches for the sludge for the second time. The hot gas is ejected from the nozzles 62 at the bottom of the second drying component 7, and the sludge is turned over and dried for the second time, thereby improving the drying effect of the sludge.
